Time-of-use tariffs

Tariff 12 Residential (Time-of-Use)

Tariff 12 is a time-of-use tariff that provides a continuous supply of electricity, with different pricing depending on the time of day that electricity is used. During the peak period between 4pm and 8pm on weekdays, Tariff 12 is priced higher than in shoulder and off-peak periods.

It cannot be used in conjunction with Tariff 11 or Tariff 13 at the same National Metering Identifier (NMI) address or to connect specific appliances. However, you can still choose to connect appliances such as your hot water system or pool pump to an economy tariff.

Tariff 13 Residential (PeakSmart Time-of-Use)

Tariff 13 is a new time-of-use tariff that provides a continuous supply of electricity, with different pricing depending on the time of day that electricity is used. During the peak period between 4pm and 8pm on weekdays, Tariff 13 is priced higher than in shoulder and off-peak periods.

It cannot be used in conjunction with Tariff 11 or Tariff 12 at the same National Metering Identifier (NMI) address or to connect specific appliances. However, you can still choose to connect appliances such as your hot water system or pool pump to an economy tariff.

To qualify for Tariff 13, you must have a PeakSmart air conditioner, which complies with AS4755.3.1 and has at least 4kW cooling capacity. Ergon Energy will supply a signal receiver that needs to be fitted within the air conditioner to enable Ergon Energy to manage the electricity use of the air conditioner during periods of peak demand or network stress.

Tariff 13 is only available in areas where the signalling system used by Ergon Energy to communicate remotely with PeakSmart air conditioners is active. Ergon Energy can identify whether Tariff 13 is available in your area during the process of requesting a change of tariff for your household.

Between 1 July 2013 and 30 June 2014, Ergon Energy is offering up to $100 cash back for customers connecting to Tariff 13 to assist with the cost of connecting the signal receiver.

Is a time-of-use tariff right for me?

Tariff 12 and 13 are generally better suited to high-use households or those who are able to shift a significant proportion of their electricity usage to outside the peak period between 4pm and 8pm on weekdays.

If you’re considering a change to Tariff 13, you’ll need to have a PeakSmart air conditioner with at least 4kW cooling capacity and have a signal receiver fitted within the air conditioner. This enables Ergon Energy to manage the electricity use of the air conditioner during periods of peak demand or network stress.

Alternatively, Tariff 12 has a similar pricing structure to Tariff 13 but without the requirement for PeakSmart air conditioning.

Take our residential tariff assessment to find out whether it’s worth considering a change of tariff for your household.

What is a daily supply charge?

The daily supply charge, also called a service fee, is a fixed amount charged to cover the costs of maintaining electricity supply to a premises, including the costs associated with electricity meter reading, the provision of equipment and general administration.

Do I need a new electricity meter?

Changing to Tariff 12 or 13 may require installation of a new meter. If new metering is required, it would be provided by Ergon Energy at no cost to you.

However, your meter board and wiring must comply with current standards before a new meter can be installed. To find out if your meter board is compliant, please check with a licensed electrician.

If the meter board or wiring needs upgrading, your electrician will need to complete the work before a new meter can be installed. Any costs associated with this work would be at your own expense.

If Ergon Energy is unable to install the meter because the meter board is not compliant, you may incur a fee.

How can I change tariffs?

Once you’ve reviewed your tariff options and decided to change your household tariff, you’ll need to complete an application.

This process will help identify whether Ergon Energy is able to offer that tariff in your area and if your household is eligible.

If changing to Tariff 13, Ergon Energy can only progress your request if your meter board is already compliant with current standards.  If it appears from your application that your meter board is not compliant, you will be notified of this requirement by email and your request to change to Tariff 13 will be closed.

You will need to arrange for a licensed electrician to assess your meter board and wiring and complete any work required to ensure it complies with current standards. Any costs associated with this work would be at your own expense.

Once your electrician has let you know that your meter board is compliant, you can then submit a new request to change your tariff.

What happens to my PeakSmart air conditioner if I leave Tariff 13?

After you change from Tariff 13 to a different residential tariff, you can arrange for a licensed electrician to disconnect the signal receiver and deactivate the air conditioner. Any costs associated with this work would be at your own expense. 

If you choose to keep the signal receiver connected, it will remain active and your PeakSmart air conditioner will continue to be managed by Ergon Energy during periods of peak demand or network stress.
